Abstract

A method for writing a file of data to a compact disc media is provided. The method begins by receiving a first portion of the file (104) for writing to the compact disc media. The first portion can be any portion of the file. Once received, the first portion is divided into a plurality of chunks (106). A map data sector is then generated for a set of the plurality of chunks (108), and the map data sector includes information for interrelating the file data and the plurality of chunks to be written to the compact disc media. The map data sector is then written to the compact disc media followed by the plurality of chunks of the first portion of the file (110). If possible, the plurality of chunks are first compressed (112) before writing to the compact disc media (114). If the first portion is long enough to fill multiple sets of chunks, associated map data sectors will be generated for those additional sets of chunks. Reading of a file written to the compact disc media will include reading the map data for the file, decompressing the file if needed and then arranging the chunks of data in accordance with information provided by the map data. The file is then transferred to the requesting application in the arranged file order.
